See it on the Bible & Christianity map →What it is
Quakers and Anglicans founded the Society for Effecting the Abolition of the Slave Trade in London in 1787. William Wilberforce, a member of Parliament converted in 1785, pressed bills year after year from 1789; Thomas Clarkson gathered evidence; the formerly enslaved Olaudah Equiano published his story (1789). Mass petitions and a sugar boycott followed. Parliament banned the British slave trade in 1807 and slavery across most of the empire in 1833. In America, Christians argued on both sides.
Why it matters
It is often called the first mass human-rights campaign, and its methods (petitions, boycotts, badges, lobbying) became the template for modern activism.
Sources and history
Parliamentary debates, petitions, Clarkson's History (1808), Wilberforce's diaries and the Acts survive; the Slave Voyages database documents about 12.5 million Africans shipped across the Atlantic.
Questions and debates
Historians weigh faith against economics (Eric Williams argued in 1944 that slavery ended when it stopped paying) and against the resistance and revolts of enslaved people themselves.

Connections (3)
▸The Great Awakenings (revivals) fueled Wilberforce and the Christian fight against slaveryHistorical record
The connection
Revivals taught that every soul is equal before God and that converts must turn from sin, including social sins. Evangelical converts like Wilberforce and the former slave-ship captain John Newton, author of 'Amazing Grace', joined Quakers to attack the slave trade; America's Second Great Awakening fed Northern abolitionism.
When and where
Britain from the 1780s, around the evangelical 'Clapham Sect'; the U.S. North from the 1830s, where Charles Finney's converts filled abolition societies.
Historical evidence
Wilberforce's 1787 journal names ending the slave trade one of two 'great objects' God set before him; Newton's Thoughts upon the African Slave Trade (1788) and church petitions survive.
Questions and debates
The same revivals also produced Southern churches that defended slavery from the Bible; why faith pointed people in opposite directions is still examined.
▸John Wesley and Methodism encouraged Wilberforce and the Christian fight against slaveryHistorical record
The connection
Wesley published Thoughts upon Slavery (1774), calling the trade a crime against justice and mercy. His last letter urged Wilberforce to 'go on' until 'American slavery (the vilest that ever saw the sun)' vanished. His Methodist followers became mainstays of the anti-slavery petition campaigns.
When and where
London: Thoughts upon Slavery, 1774; the letter to Wilberforce is dated February 24, 1791, six days before Wesley's death.
Historical evidence
Both texts survive; Wilberforce kept the letter, and Methodist conference minutes and petition rolls record Methodist support.
Questions and debates
How much Wesley moved Wilberforce, already committed since 1787, is unclear; American Methodists later softened their anti-slavery rules and split over slavery in 1844.
▸Martin Luther King Jr. and civil rights continued the struggle of Wilberforce and the Christian fight against slaveryHistorical record
The connection
King saw civil rights as finishing what abolition began. 'I Have a Dream' opens by recalling Lincoln's Emancipation Proclamation and saying that 'one hundred years later, the Negro still is not free.' His line that 'the arc of the moral universe is long, but it bends toward justice' paraphrased abolitionist minister Theodore Parker (1853).
When and where
Lincoln Memorial, Washington, August 28, 1963; King's speeches and sermons of the 1950s–60s, rooted in Black churches founded in abolition's era.
Historical evidence
The speech texts and recordings, and Parker's published sermon; historians link both movements through Black churches and their reading of the Bible.
Questions and debates
Historians debate the 'long civil rights movement' idea: whether one unbroken struggle ran from abolition to King, or distinct movements with different goals.
